Method of Moments for 2D Scattering Problems. Basic Concepts and Applications

Electromagnetic wave scattering from randomly rough surfaces in the presence of scatterers is an active, interdisciplinary area of research with myriad practical applications in fields such as optics, acoustics, geoscience and remote sensing. In this book, the Method of Moments (MoM) is applied to compute the field scattered by scatterers such as canonical objects (cylinder or plate) or a randomly rough surface, and also by an object above or below a random rough surface. Since the problem is considered to be 2D, the integral equations (IEs) are scalar and only the TE (transverse electric) and TM (transverse magnetic) polarizations are addressed (no cross-polarizations occur). In Chapter 1, the MoM is applied to convert the IEs into a linear system, while Chapter 2 compares the MoM with the exact solution of the field scattered by a cylinder in free space, and with the Physical Optics (PO) approximation for the scattering from a plate in free space. Chapter 3 presents numerical results, obtained from the MoM, of the coherent and incoherent intensities scattered by a random rough surface and an object below a random rough surface. The final chapter presents the same results as in Chapter 3, but for an object above a random rough surface. In these last two chapters, the coupling between the two scatterers is also studied in detail by inverting the impedance matrix by blocks. Contents 1. Integral Equations for a Single Scatterer: Method of Moments and Rough Surfaces. 2. Validation of the Method of Moments for a Single Scatterer. 3. Scattering from Two Illuminated Scatterers. 4. Scattering from Two Scatterers Where Only One is Illuminated. Appendix. Matlab Codes. About the Authors Christophe Bourlier works at the IETR (Institut d’Electronique et de Télécommunications de Rennes) laboratory at Polytech Nantes (University of Nantes, France) as well as being a Researcher at the French National Center for Scientific Research (CNRS) on electromagnetic wave scattering from rough surfaces and objects for remote sensing applications and radar signatures. He is the author of more than 160 journal articles and conference papers. Nicolas Pinel is currently working as a Research Engineer at the IETR laboratory at Polytech Nantes and is about to join Alyotech Technologies in Rennes, France. His research interests are in the areas of radar and optical remote sensing, scattering and propagation. In particular, he works on asymptotic methods of electromagnetic wave scattering from random rough surfaces and layers. Gildas Kubické is in charge of the “Expertise in electroMagnetism and Computation” (EMC) laboratory at theDGA (Direction Générale de l’Armement), French Ministry of Defense, where he works in the field of radar signatures and electromagnetic stealth. His research interests include electromagnetic scattering and radar cross-section modeling.

Nicolas Pinel (?-1655) ou Nicolas Pinel dit "Lafrance" est un marchand français qui fut l'un des pionniers de la Nouvelle-France.

C'est le fils de Jean Pinel et de Thomasse de la Haye de Campagnolles (Normandie).

Il se marie à La Rochelle le 29 septembre 1630 et y fait baptiser quatre enfants entre 1631 et 1636.

Le 5 avril 1645, toujours à La Rochelle, Nicolas s’engagea à aller travailler pendant trois ans à Port-Royal en Acadie, en tant que scieur de long et charpentier de grosses œuvres. Nicolas laissait en France sa femme, Madeleine Maraut, et ses enfants. A l’expiration de son engagement, Pinel ne retourna pas en France. La famille Pinel arrive en fait à Québec après la fin de l’engagement de Nicolas à Port-Royal, quelque part donc entre 1647 et 1650.

On le retrouve à Québec où, le 16 septembre 1650, il s’engage envers Anne Gasnier à faire valoir sa terre de Monceaux durant deux ans[1]. Bien que fermier d’Anne Gasnier, Nicolas Pinel possède en propre, probablement depuis 1651, une terre près de la rivière du Cap Rouge[2].

Le 27 avril 1651, il est attaqué avec son fils Gilles Pinel par deux Iroquois[3].

Et le 23 janvier 1652, il acquiert des Jésuites une nouvelle terre sur le bord du fleuve à Sillery[4].

Il mourut à l’hôpital Hôtel Dieu de Québec le 18 septembre 1655 de blessures causées par une arquebuse.

Les Pinel et un grand nombre de Lafrance du Canada descendent de Nicolas Pinel et de Madeleine Maraud.

Une rue et un parc de Québec dans l'arrondissement Sainte-Foy–Sillery porte le nom de Nicolas-Pinel en son honneur.
